Umuyoboro winyuma ni igice kimwe kigizwe nibice bitatu byubwubatsi. Mubisanzwe bizwi nka "uhuze kumpande zombi". Mugihe cyo kubaka, uyikoresha akeneye gusa guhindura intebe kugirango ahindure akazi. Akazi nyamukuru k'umutwaro winyuma ni ugucukura imyobo igana imiyoboro hamwe ninsinga zubutaka, gushiraho urufatiro rwinyubako no gushyiraho uburyo bwo kuvoma.
Impamvu nyamukuru abatwara backhoe bari kumwanya wubwubatsi ni ukubera gukenera gucukura no kwimura umwanda kubikorwa bitandukanye. Mugihe ibindi bikoresho byinshi bishobora gukora akazi nkuyu, umutwaro winyuma urashobora kongera imikorere yawe kuburyo bugaragara. Mugereranije, abatwara imizigo yinyuma iroroshye kuruta ibikoresho binini, bigamije intego imwe nka moteri ya crawler. Kandi zirashobora kandi kwimurwa hafi yubwubatsi butandukanye ndetse no kwiruka mumuhanda. Mugihe ibikoresho bito bito hamwe nubucukuzi bishobora kuba bito kurenza umutwaro winyuma, ukoresheje umutwaro winyuma urashobora kubika umwanya munini namafaranga mugihe rwiyemezamirimo akora ibikorwa byo gucukura no gupakira.
Ibigize
Umuyoboro winyuma urimo: powertrain, imizigo irangira, nubucukuzi bwanyuma. Buri gice cyibikoresho cyagenewe ubwoko bwakazi. Ahantu hasanzwe hubakwa, abashinzwe gucukura akenshi bakeneye gukoresha ibice bitatu byose kugirango akazi karangire.
Powertrain
Imiterere yibanze yumutwaro winyuma ni powertrain. Powertrain yumutwaro winyuma yagenewe gukora kubuntu kubutaka butandukanye. Kugaragaza moteri ikomeye ya turbodiesel, amapine manini yinini yinyo hamwe na cab ifite ibikoresho byo kugenzura (ibizunguruka, feri, nibindi)
Igice cy'umutwaro
Imizigo ikusanyirizwa imbere yibikoresho naho moteri ikusanyirizwa inyuma. Ibi bice byombi bitanga imirimo itandukanye rwose. Abatwara ibintu barashobora gukora imirimo myinshi itandukanye. Mubisabwa byinshi, urashobora kubitekereza nkumukungugu munini ukomeye cyangwa ikawa. Mubisanzwe ntabwo ikoreshwa mubucukuzi, ariko ikoreshwa cyane cyane mugutora no kwimura ibintu byinshi bidakabije. Ubundi, irashobora gukoreshwa mugusunika isi nkumuhoro, cyangwa gutunganya ubutaka nkamavuta kumugati. Umukoresha arashobora kugenzura umutwara mugihe atwaye traktori.
Igice cyo gucukura
Gucukumbura nigikoresho nyamukuru cyumutwaro winyuma. Irashobora gukoreshwa mu gucukura ibintu byinshi, ibintu bikomeye (akenshi ubutaka) cyangwa kuzamura ibintu biremereye (nkibisanduku byimyanda). Umucukuzi arashobora kuzamura ibikoresho akabishyira kuruhande rwumwobo. Muri make, imashini ikora ni imbaraga, ukuboko cyangwa urutoki runini, bigizwe n'ibice bitatu: gutera imbere, indobo, n'indobo.
Gutuza ibirenge
Ibindi byongeweho mubisanzwe biboneka kubatwara inyuma harimo ibirenge bibiri bihagarara inyuma yibiziga byinyuma. Ibi birenge nibyingenzi mumikorere ya moteri. Ibirenge bikurura ingaruka zuburemere bwa excavator mugihe ikora ibikorwa byo gucukura. Hatabayeho guhagarika ibirenge, uburemere bwumutwaro uremereye cyangwa imbaraga zo hasi zo gucukura byangiza ibiziga nipine, kandi romoruki yose izasunika hejuru. Guhagarika ibirenge bituma traktor itajegajega kandi bikagabanya imbaraga zatewe nigihe ubucukuzi bwacukuye. Guhagarika ibirenge kandi birinda traktor kunyerera mu mwobo cyangwa mu buvumo.
